DARIUS B. SMITH, OF PINE MEADOVV, CONNECTICUT.

FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 325,982, datedSeptember 8, 1885. Application filed May 2, 1885. (No model.)

To all whom it may concern.-

Beit known that I, DARIUs B. SMITH, a citizen of the United States,residing at Pine Meadow, in the county of Litchfield and State ofConnecticut, have invented certain new and useful Improvements inFire-Extinguishers; and I do declare the following to be a full,clear,and exact -description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and tothe letters andfigures of reference marked thereon, which form a parti of thisspecification.

The object of this improvement is a device to be attached towater-pipesin factories or other buildings, that will be p ut inoperawww.

tion by the temperature resulting from the presence of re, and cause aneffective divergent issue of water from the pipes with which connectionis made, for the purpose of arresting the progress of and extinguishingconilagrations. These results are attained by the mechanismillustrated'in the drawings herewith iiled as part hereof, in which thesame letters of reference denote the same parts in the different views.

Figure 1 is a side elevation, partly in section, of a nre-extinguisherembodying thekfeatures of my improvement. Fig. 2 is a vw of the same,showing parts in an adjusted position preceding the action of the otherparts.

Fig. 3 is a vertical sectional view. Fig. 4 is a view of one of theparts` detached. Fig. 5 is a transverse section of the same. Fig. 6 is atop View of the link. Fig. 7 is a longitudinal vertical section thereofwith the parts connected. Fig. 8 represents the parts of the link thatare connected by fusible solder previous to the application of thesolder.

A is a nozzle, having arms B B, connecting with areccssed head or yoke,B', all made integral.

C is a screw-threaded extension of the nozzle A, having an oppositeextension, D, for a purpose hereinafter set forth.

G G' represent clamps pivoted to and within the recessed head or yokeB', as shown at g, and provided each with semicircular screwthreadedrecesses G, which correspond in size and thread with a bolt, H, havingat its lower part a shoulder, h, an integral wrench-nut, h', and atapering point,which enters a corresponding recess, E', of a nozzle-cap,E, having a concaved recess and horizontal inner bearing provided with agasket, d, which mayk be of any suitable material, of sufficient sizetocover` the nozzle-extension D.

K K' represent plates made of brass or other suitable metal, andslightly cut away at their inner ends, and provided iwith perforation'sfor the reception of fusible solder k', by means of which they areconnected into a link having eyes It? near their outer ends, which fitover .the arms of the clamps G G' and hold the same together, as shownin Fig. 1, and

hold the same in proper relative position to the nozzle to cause adivergent issue or distribution of water therefrom.`

The solder .connecting theplates K K' will be acted upon by a degree ofheat equal to the temperature of boiling water, -when the pressure ofthe water and the gravity of the parts will cause the plates vK K' to bedisconnected completely, when the clamps G G' will take the positionshown in Fig. 2, and allow the bolt H and the cap E to move away fromthe noz.- zle, and thus give action to the water in the pipes, to whichthe mechanism is to be attached in a pendent manner by means of thescrew-threaded nozzle-extension C.

. Having explained the construction and operation of my improvement,what I claim as new, and desire to secure by Letters Patent, Is-

ing arms B B, terminating in a recessed head or yoke, B', all madeintegral, the clamps G G', provided with semicircular screw-threadedrecesses G2, and pivotally connected to the yoke B', the fusible linkconstructed as described, the bolt H, and `nozzle-cap E, all arranged tooperate as and for the purpose set forth.

In testimony whereof I aftix my signature in presence of two Witnesses.
